I have heard that small recurring donations are more helpful in general than larger one-time donations, so that's what I tend to do - small recurring donations to services I use or creators whose content I consume. I tend to only do this when the service or content is primarily donation-supported, though.

This is also easier for me to manage, because it becomes a monthly recurring cost and I can see easily how much I'm spending on donations and adjust them as needed, whereas with larger one-time donations, I tend to lose track of how much the total is in a given period.
